[Serusers] Problem with CANCEL and INVITE

[Benito Caracuel]

Hello all,

UAC -------------- SER ----------------- UAS

INVITE ---------->INVITE------------>INVITE

          <----------TRYING

CANCEL------------>

          <-----------TRYING


If UAC sends an INVITE and then  sends a CANCEL, this CANCEL doesn't stop 
SER.
SER is still processing  the INVITE to UAS, why?

Help me please.
Thank you.
